Operating Parameters
The OIT has many operating parameters which determine how it communicates to the
host controller. These operating parameters can be changed in three ways: from the OIT’s
keyboard when the OIT is in Configuration mode, when the host controller sends a
Configuration Control Command, or by downloading a STEPware-100 project. Each
operating parameter is described in detail below.
Display Viewing Angle Setting
The OIT has an adjustable viewing angle of 75° and 90°. A viewing angle of 75º means
that the LCD provides the sharpest contrast when viewed from a point slightly below the
display. An angle of 90º means that the sharpest contrast occurs when the LCD is viewed
from a point perpendicular to the face of the display.
Factory Default: 90
°
To modify this parameter using STEPware-100:
1. Open the Configuration Editor.
2. In the OIT Display (LCD) group box, select the desired Viewing Angle from the
option buttons.
To modify this parameter in Configuration mode:
1. At Disp View Angle:, select the desired Viewing Angle. Refer to the Configuration
Mode section in this chapter for more information.
To modify this parameter from the host controller:
1. Use the Set LCD Viewing Angle control command. Refer to Appendix A: Control
Commands for more information.
Baud Rate Setting
This parameter determines the baud rate that the OIT uses to communicate to the host
controller. Options are 300, 600, 1200, 2400, 4800, 9600, and 19200 baud. When the OIT
is in Configuration mode, 9600 baud is used to communicate to STEPware-100
regardless of how this setting has been configured.
Factory Default: 9600
To modify this parameter using STEPware-100:
1. Open the Configuration Editor.
2. In the OIT - Host Serial Communications Settings group box, select the desired baud
rate from the Baud Rate option buttons.
To modify this parameter in Configuration mode:
1. At Baud Rate:, use the OIT’s Period (.) key to select the desired baud rate. Refer to
the Configuration Mode section in this chapter for more information.
To modify this parameter from the host controller:
1. Use the Set Communications Parameters control command. Refer to Appendix A:
Control Commands for more information.
